Gubernatorial and legislative party control of state government refers to the role ofpolitical parties in the power dynamic between state legislatures and executives. Below, we examine the partisan affiliation of the 1,973state senators, 5,413state representatives, and 50state governors across the United States.

Below, Ballotpedia presents our information on the partisan breakdown of state senators, state representatives, and governors as well as the state legislature and state executive branch as a whole. We also examine state governmenttrifectas, which occur when the state house, the state senate, and the office of the governor are each controlled by one political party. Trifectas are important to highlight since unified partisan affiliation between the branches of state government can impact a state's legislative process.
